Abstract
A stator manufacturing method which manufactures an insulated conductor coil and mounts this coil to the core, the insulated conductor coil being formed by deforming an insulated conductor into a shape having rectilinear in-slot conductor sections and coil end sections having bent sections, the conductor having an enamel layer formed on the outer periphery thereof and also having an extruded resin coating layer formed on the outer periphery of the enamel layer, comprises: a first step of forming the conductor coil by deforming the conductor to form the bent sections while the coating layer of the conductor is in a non-crystalline resin state; a second step of heating the extruded resin coating layer of the conductor coil to change into a crystalline resin state to a temperature higher than or equal to the glass transition temperature; and a third step of mounting the conductor coil to the core.
